Question

您好我正在使用如下所示的json文件：

{
    "workspace_id": "car-dashboard-en",
    "name": "Car Dashboard - Sample",
    "created": "2017-03-20T21:24:41.498Z",
    "intents": [
      {
        "intent": "about_VA",
        "created": "2017-03-14T02:02:16.290Z",
        "updated": "2017-03-14T02:02:16.290Z",
        "examples": [
          {
            "text": "any music reccomendation?",
            "created": "2017-03-14T02:02:16.290Z",
            "updated": "2017-03-14T02:02:16.290Z"
          },
          {
            "text": "can you recommend ood jazz music?",
            "created": "2017-03-14T02:02:16.290Z",
            "updated": "2017-03-14T02:02:16.290Z"
          },
          {
            "text": "cloud you recommend music?",
            "created": "2017-03-14T02:02:16.290Z",
            "updated": "2017-03-14T02:02:16.290Z"
          },
          {
            "text": "your name",
            "created": "2017-03-14T02:02:16.290Z",
            "updated": "2017-03-14T02:02:16.290Z"
          }
        ],
        "description": null
      },
      {
        "intent": "capabilities",
        "created": "2017-03-14T02:02:16.290Z",
        "updated": "2017-03-14T02:02:16.290Z",
        "examples": [
          {
            "text": "adapt to current weather condition",
            "created": "2017-03-14T02:02:16.290Z",
            "updated": "2017-03-14T02:02:16.290Z"
          },
          {
            "text": "book a flight for NY on sunday",
            "created": "2017-03-14T02:02:16.290Z",
            "updated": "2017-03-14T02:02:16.290Z"
          },

          {
            "text": "can you change lanes",
            "created": "2017-03-14T02:02:16.290Z",
            "updated": "2017-03-14T02:02:16.290Z"
          },

我有一个json有一个名为＆＃39; intents＆＃39;这部分由几个意图组成，每个意图都有一个名为＆＃39; text＆＃39;，

的值列表

我想从这个文件中提取一个字典，如下所示：

dictionary = {'intent_name':[text1,text1,text3,...],'intent_name2':[text1,text2,text3,...],...}

此词典的关键是相关意图的名称，值是此意图的每个文本，

不幸的是我是一个使用json文件的初学者，所以我尝试了：

import json

with open('workspace-car-dashboard-en.json') as json_file:  
    data = json.load(json_file)

使用以下代码我将提取并打印所有文本值，如下所示：

for element in data['intents']:
    for element2 in element['examples']:
        print(element2['text'])

我得到了：

any music reccomendation?
can you recommend ood jazz music?
cloud you recommend music?
do you hate
Do you like
do you love

但是我无法动态构建字典并附加所有文本值，所以我真的很感谢支持来完成这项艰巨的任务。我无法包含完整的json文件，因为它非常大，所以我希望这个例子足够了。

创建一个新的空字典。添加每个意图名称的键并设置空列表的值。然后使用您创建的示例文本从循环中插入每个文本键值。

import json

with open('workspace-car-dashboard-en.json') as json_file:
    data = json.load(json_file)

new_dic = {}
for element in data['intents']:
    new_dic[element['intent']] = []
    for element2 in element['examples']:
        new_dic[element['intent']] += [element2['text']]

如何从json文件构建以下字典？
